Brinkman Number
The Brinkman number (Br) is a dimensionless number related to heat conduction from a wall to a flowing viscous fluid, commonly used in polymer processing. It is named after the Dutch mathematician and physicist Henri Brinkman. There are several definitions; one is \mathrm = \frac = \mathrm \, \mathrm where * ''μ'' is the dynamic viscosity; * ''u'' is the flow velocity; * ''κ'' is the thermal conductivity The thermal conductivity of a material is a measure of its ability to conduct heat. It is commonly denoted by k, \lambda, or \kappa. Heat transfer occurs at a lower rate in materials of low thermal conductivity than in materials of high thermal ...; * ''T0'' is the bulk fluid temperature; * ''Tw'' is the wall temperature; * Pr is the Prandtl number * Ec is the Eckert number It is the ratio between heat produced by viscous dissipation and heat transported by molecular conduction. i.e., the ratio of viscous heat generation to external heating. The higher its value, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
